I care about your privacy and security. That’s why I’ve made it easy for  you to contact me securely by end-to-end encrypted message, call, and email. Below you can read more about why I think it’s important to use  secure channels for communication.

For a condensed overview, see my about page.

End-to-End Encrypted Email

My email is [email protected].

My main X25519 public key can be downloaded here and is pasted below. The fingerprint is 65DB 8A03 3ED5 3365 91BB 36EB 42F1 8CF1 1653 DD14.

If you’re unsure how to use PGP encrypted email, I invite you to sign up for a free email address at ProtonMail, an email provider that makes it easy to use end-to-end encryption with email.

Of course, you can also email me without end-to-end encryption as you might normally do, but I encourage you to use it.

Alternatively, you can also email me at [email protected]. The fingerprint is 64E1 BACB 2D48 C7F0 8C31 41CA 8915 ABDB 0ADE 1440.

64E1 BACB 2D48 C7F0 8C31 41CA 8915 ABDB 0ADE 1440

To send me large files via end-to-end encryption, you can use Firefox Send. If you assign a password, make sure you send it to me.

Snail Mail

I accept snail mail at the following address:

Theodore Chu
PO Box 8222
Foster City, CA 94404

or

Theodore Chu
750 Alma Ln #8222
Foster City, CA 94404

Anonymous Contact

You can email me with a disposable email address such as those provided by Guerilla Mail (Tor). You might want to use the Tor Browser, a VPN, and an internet provider that’s not your home or work network. If you sign up for a free ProtonMail account, you might have access to a free trial to ProtonVPN, a VPN that integrates itself with the Tor network.

Why Secure Communications Matter

Some people tell me that they don’t need to use secure communication because they have nothing to hide. I like to acknowledge that it is  their choice not to use it, but that there are many people in our society whom we would want to have access to privacy and security because they handle sensitive information about themselves or others and  by using it, we can indirectly support them.

These people include doctors, lawyers, journalists, activists, whistleblowers, accountants, real estate agents, LGBTIQA+ youth,  political leaders, human rights defenders, nonviolent protestors,  academic researchers and those who live and work with them. A loss of  privacy or security for these people would likely threaten the  well-being of themselves and everyone else involved.

We depend heavily on many of these people to provide institutions and services that help maintain our health, well-being, and freedom. By using secure communications, we can create a culture that better respects and appreciates their work and lives. When we participate in  and contribute to the culture of secure communications, we help develop  the infrastructure that these people depend on. We can help protect and  promote our democracy by allowing minority groups to reach each other,  point out hidden problems, and voice their opinions.

So, even if you don’t have anything to hide, there is a lot you may gain from joining the movement towards a more secure and private internet. I invite you to join me. Besides, practicing secure communications is a habit that takes time to adopt and you might being  one of those people we depend on before you know it.
